Zero emission power plants

Several other countries are also planning to build zero-emission power plants. The GreenGen Project, started in 2005 in China, will employ hydrogen to generate power and will include a C02-sequestering system.

These funds will enable TxEC to gain access to " 3.6 million to match local startup funds, 2.5 million to put toward Texas bid for management of an anticipated 2 billion in federal funds, earmarked for an ultra-deepwater research program, 10 million to develop zero-emissions power plant technology, and 15 million to develop a statewide fuel cell industry." ...

The World Bank grants financing for fossil fuel electricity generation, yet finances only facilities that have advanced emission control equipment. And although the World Bank has never financed a nuclear power plant, a zero carbon emitter, it is vciy active in evaluating hydropower projects, helping to establish the World Commission on Large Dams.

Recent studies have addressed the combustion of natural gas with pure oxygen, highly diluted with exhaust gases (CO2 and H2O) in order to mitigate both NO and CO2 emissions from power plants. The so-called oxy-fuel combustion includes an air separation unit, which delivers O2 to the catalytic stage, where it is mixed with natural gas and the exhaust recycle stream. An example is the Advanced Zero Emission GT, first jointly studied by Norsk Hydro and ABB Alstom Power [28-31].

Secondly I think one has to look very carefully at transport phenomena. Several speakers in this Study Week have referred to the effect of the introduction of tall stacks which permit an increased dilution of emissions from power plants. The inclusion of a tall stack at a power plant does not cut the deposition in the vicinity of that stack — and you can use the term vicinity in any way you like — to zero and the deposition at a distance of 500 kilometers to 100%. A very substantial fraction of the deposition associated with emission from a particular source, even with the tall stack, occurs relatively near to that source and again, the question of how near is one, that is extremely difficult to get solid answers for — one simply does not have that kind of information. If you want to take an applied mathematician and send him into shock, you ask him to model the flow from a tall smokestack over a distance of about ten or twenty kilometers — that is just something that is not done. The overall transport phenomenon in acid rain is an extraordinarily complex multi-scale phenomenon. So far as the chemistry is concerned, I think that, too, varies dramatically with the climate, with the season, with the presence of oxidants of various types in the atmosphere, and I fear that there can be no single generalization concerning acid rain and the mitigation of acid deposition worldwide. This is something that has to be handled on a scale which in fact I think will be much smaller.
